This is currently true, but should be fixed this year (probably not this month -- it depends on how much energy I have). Draft 4 (draft 5 isn't out yet) of POSIX.1-200x says the following (p. 411, ll. 13759 et seq): The id_t and pid_t types shall be defined as described in <sys/types.h>. [begin XSI] The siginfo_t type shall be defined as described in <signal.h>. The rusage structure shall be defined as described in <sys/resource.h>. Inclusion of the <sys/wait.h> header may also make visible all symbols from <signal.h> and <sys/resource.h>. [end XSI] So, <sys/types.h> is not a prerequisite for 1003.1-200x's <sys/wait.h>. For the XSI extension, implementors are given special license for certain XSI-required data types (which, being structures, are somewhat impractical to define in the usual way); in a pure-POSIX environment <sys/types.h> is not permitted. According to the revision history (p. 412), this is a requirement carried over from SUSv2 and dates back to XPG4v2. -GAWollman -- Garrett A.
